To all fw hom l? may concern:

Be it known that I, EDWARD G. DOYEN, a citizen of the United States,residing at San Francisco, in thecounty of San Francisco, State ofCalifornia, have invented a new and useful Mattiess-lut'ting Machine, ofwhich the following is a specication in such full and clear terms aswill enable those skilled in the art to construct and use the same.

This invention relates to a mattress tufting machine and its object isto provide amachine which will be capable or pushing all of the needlesforA one transverse row of tufting through the mattress at one time,after which the Yneedles are removed and shifted several inches to placeanother transverse row of tufting.

1t will be understood by tho'seskilled in the art that in tuttinga-mattress a long needle is used, and is pushed through the mattressfrom one side to the other, whereupon one tut't is inserted under theloop of the string and thev needle is then withdrawn and another tutt isthen tied against the opposite side of the mattress and the first tuttto prevent the mattress filling from shifting when the mattress is inuse.

\ With the present invention enough needles are used to tuft onecomplete transverse row at one time, all of the needles being carried bya frame which pushes them through the mattress at one time.

Another object ot the invention is to pro,

Another'object of the invention is to pro- A vide means whereby themattress will be held down during the time the needles are-being pushedthrough it. l

Another object ot the invention is to arrange the operation so as. toprevent the strings used from being pulled` out of p lace during thetime the mattress is being worked upon, the strings being cut after thetufts have all been inserted on one side of the mattress.

Other objects of the invention will appear as the description proceeds.d

An embodiment of the invention is shown in the drawings in which thesame numeral reference is applied to the same portion throughout, but 1am aware there may be modifications thereof.

Figure 1 is a plan view of the vcomplete machine.

Figure 2 is a sectional end view on line 2-2 of Fig. 3.

Figure 3 is a side elevation of the complete machine.

Figure 4 isa view of a portion ot' the mattress and one needleillustrating the manner of tying in the tufts.

The machine comprises four supporting posts 1 to 4.inclusive. Theseposts are connected together by two side rails 5 and (Sand bytwotransversally extending side rails 7 and 8, which are in turn connectedto the posts by means of two braces 9 and 10 at each end.

At the top the posts are connected together by two transverse stringere11 and 12 at one end and stringers 13 and 14 at the other end. AThesestringere being separated by spacing members' 15 and 16 but whichspacing members are not 'as wide vas the members which they space,

Extending into the grooves produced between the members 11 and 12 and 13and 14 are two iixed slats 18 and 19 and seven adjustableslats 20 tov26inclusive. There are used such number of adjustable slats as is requiredto produce the proper number of supports for the number of -needles usedon any given mattress.

Each of the rails 5 and 6 has a longitudinally extending track as shownat 27 and 28, each of the tracks supporting a two wheeled carriage 30,the wheels being indicated at 31 and 32 in dotted lines.

Depending from the carriage 30 are two bars 33 and 34, which areconnected by a bottom cross bar 35. The bottom cross bar 35 is connectedto the two depending bars 33 and 34 by means of two braces 36 and 37.The depending bars 33 and 34 carry guides 38and 39 in which arectangular frame, having the horizontal members 40 and 41 and endmembers 42 and 43, is vertically slidable.

Each of the depending bars 33 and 34 has a block as indicated at 44 and45, said block v supporting guides 46 and 47 through which two slidablebars 48 and 49` move.

The carriage 30 has guides 50 and 51 through which the two bars 48 and49 pass.l

'70 operated by means of knobs 7l.

Bolted on the sides of dependingr bars 33 nhorizontal member 40 ofneedle frame, by

means of two links 57 and 58. At the end of each lever there is astirrup 59 and 60, for the use of the operator.

The slidable bars 48 and 49 carry two cross bars 62 land 63, which areseparated from each other far enough to permit the necessary space forthe operator to accomplish the tufting when the needles have been pushedthrough, and said bars hold the mattress down when the entire set ofneedles is being pushed through it.

The slidable bars 48 and 49 are .connected to the levers 55 and 56 bylinks 65 and 66, and-both levers 55 and 56 and said links'65 and 66 areprovided with a plurality of holes so as to adjust the height of crossbars 62 and 63 to correspond with the thickness of the mattress beingtufted, and the length of the bars is arranged so that the needles willjust show through, as shown in Fig. 4, when the mattress is pressed downtightly by cross bars 62 and 63.

The tufting needles are indicated at 67 and they are carried byadjustable slides 68 on the horizontal member 41. These slides are heldin any given adjustment by means of set screws 69. In order to providefor the automatic adjustment of the position of the needles followingeach tufting operation, the carriages 30 are provided with stiff springsThese springs engage notches on a steel plate 72, supported by a rail 73extendingr between the posts. There is a rail 73 at eachv side of themachine` and a spring for each carria e 30.

ach carriage 30 is also connected to a cable 74 which extends around apulley 75 at one end of the machine, and over a pulley 76 on the ceilingof the room in which the machine is installed, and at its end it isprovided with weights 77, so that when the spring is removed from thenotches the weights cause the carriage carrying the needles to move tothe next position auto@ -matical1y.

The operation of the apparatus is as fol lows:

Assuming the needles to be threaded with a suitable heavy cord or twine,one end of said cord is knotted as indicated at 78, and the operators,one at each side of the machine, press upon the stirrups 59 and 60,causing the needles to press up through the mattress, 'thereupon a tuft79 is placed under the loop of string 80; the needles are removed andshifted to another position, whereupon another tuft 81 is inserted inthe loop of the 'string and the operationl continues to the ing a framehaving supports for the mat-l tress, a cross bar extending over themattress to prevent 1t from rising, a frame carrying a plurality ofneedles and with lwhich said cross bar is movable, levers for raisingthe frame carrying the needles and depress-y ing the bar above themattress, side rails carried by the vfirst frame, a slidable carriagemovable along said side rails to which the needle carrying frame issecured, and a gauge along side the mattress support for spacing thetufts. p
